[TRNSYS-users] Trnsys 17 coupling Contam: multipliers

[David BRADLEY]

Moises,
If you are working with TRNSYS 17 then that is good! Trnsys17 has a more 
logical way of dealing with those multipliers. Essentially the control 
signals that open or close a certain path become inputs to the model. 
Please refer to the Type97 description in the 04-Mathematical Reference 
manual for instructions on how to pass your control variables to Type97; 
some manual editing of the *.air file is necessary but it is also pretty 
straight forward.
Kind regards,
David
